CLAMPING DEVICE Filed June 23, 1941 Patented Feb. 1%, 1942 pair sr rrics 11 Claims.

This; invention relatesto a: clamping device to hold; a: rope: to a thimble".

The principal object of: my invention: is to pro vide a' simple; mechanical: clamping device: that can: easily andi quicklyi'be tightened to hold a roperfast to, a thimble: while it is being spliced orotherwise. worked upon.

Another. object is to so constructsaid clamping: device. that its. cost' of production is relatively small; thatis'durable', and; that is adapted. for use with various sizes of thimbles and ropes;

A further'cbjectisito. provide an operable construction: of said device so. that the clamping membenthat holds the: rope fast at one side otthe. thimble. can'be completely tightened independently of the other clamping member.

The foregoing and other objects which will appear as. the nature of the invention is better understood; may be? accomplished by a construction,.ccmbination; and: operative arrangement of parts. such as-is: disclosed. by the drawing and specifications. The nature of the invention is suchzasto renderitsusceptible to various changes and modificati'onsx. and; therefore, I am not to be limited tosaid. disclosure; but am entitled to all' such changes therefrom: as: fall within the scope ofmy claims.

In the. drawing :1

Figurei2 Y is; a. front. elevational view showing a modified. fornroimy clamping deviceholding a rope fast'on a thimble.

Figure 3 is a sectional view taken on the line 3: 31 of Figure 1-.

Figurel: is a frontielevational view; partly in section,. showing my clamping device holding a rope; on- .a..thimble with a-spacer member in the openingi'n; saidi thimble to thereby keep: said. device. higher upon said: thimble;

Asillustrate'd, my clamping device has two U shaped; members. Ill? and II each embodying a pair: of'arms Ifla and Na spaced apart, and a weir Ifiband H b: connecting said pair of arms together. At their; open or free end portion there are: holes I l: extending. through said arms Illa and; I lag. said: holes ii in the pair of said arms of each :said. U-sh'aped member being in alinement-so: that axbolt B may extend through bothof them.. Itwill be observed that said arms I'Ba o-fsaidmember Ill 'are nearer together than the said arms. I la of' the said member II, thereby permitting said arms Illa to extend into the space between said: arms I'Im, whereby the. two pairs oi -said: armsoverlap: each other, This enables a single said bolt B or other form of pin member'toextend through said four holes M, first extending through said arm Ila then through said two arms Illa and then through the other said arm I la; thus holding the end portions of the arms. of both said members Illand II in position opposite the opening in a rope thimble T which has a channel C in its outer surface.

Said" connecting'webs. Illb and Ho of said U- shaped members Ill and H each have a screwthreaded aperture I6 therein and a set screw Il makes screw-threaded engagement therewith and extends thereth-rough. Fastened at the innerendaofl said set: screw I l is-asaddle I 9-whiclr preferably has a groove in the face surface thereof and which is wedge-shaped so that it will hear more evenl-y 'against the rope R-that extends" around said thimble When said screw I l istightenedsaid-saddle I-bbears against said rope" R- and-holds'it' firmly, in said channel C. It' willbeobserved that said screw H can be moved independently of all other moving parts so. that the rope1R on one: side of said thimble T can be clamped fast thereto irrespective of what is done to said: rope R at the other side of said thimble.

When his desiredto hold my clamping device at a predetermined-1 point onsaid thimble T I provide an' open spacer member 26 that is adaptedztofit in-the lower part of the opening insaid thimble- Said boltB extends through theopeningirr said insert member 20; and thus my device is'held in the desired position in said' thimble T.

In Figure 2: of the drawing l show a modified form of said U-shaped members Ill and I I in which: said. arms Illa and I Ia have extended portions 22. which extend downwardly at an angle to: the remainder of said arm; Said exten-. sions"2-2= have said holes I4 therein and they. enable the'user tokeep my: clamping device farther up onisaid thimbl'eT. and thuskeep it'out of the way of a' vise that is used to hold a thimble should that be necessary.

Myinventioniis'adaptedto hold fabric or wire rope or cables generally to saidthimble T. When said: bolt B: extends through said holes I4 in said members Ill and-II and is kept in place by a nut or otherwise, andwhen said set screws I! are tightenedtto thereby forcelsaid saddles Illagainst said rope-'R, the clamping operation is complete and'ris; all that'is': needed to hold said rope in position while it is: being spliced or otherwise worked upon. I

What I'claim is: 1. A clamping device to hold rope to a thimble comprising two U-shaped members each embodying two arms and a connecting web, the said arms of one said member being spaced apart a shorter distance than the arms of the other said member whereby they may be inserted'between' said arms of the latter said member, said arms of each said member having holes therein at their outer end portions that are in alinement whereby said members can be held together by a pin member extending through said four holes, said webs each having a threaded aperture therein and each having a screwthreaded member screw-threadedly extending into said aperture.
